Comment 69 for bug 1861610

@Frenec:
Ok, I simply commented out my lines:

Method (_STA, 0, NotSerialized) // _STA: Status
{
// If ((TPTY == Zero))
// {
// Return (Zero)
// }
// Else
// {
      Return (0x0F)
// }
}

Then I follow your description with the new sed line. Instead of
<< find kernel | cpio -H newc --create > /boot/acpi_fixed.cpio
I had to do
<< find kernel | cpio -H newc --create > ./acpi_fixed.cpio
<< sudo move acpi_fixed.cpio /boot
but that shouldn't change a thing, right?

Unfortunately, didn't work for me.
